fix: add explicit permissions to test workflows

[hyunhee-jo]

Objective

Code scanning flagged 3 alerts — test.yml and test-full.yml use default
read-write permissions when they only need read access.

Approach

Add permissions: contents: read to both workflows to follow the
principle of least privilege.

Evidence

Resolves all 3 code-scanning alerts:

Alert	File	Status
#1	.github/workflows/test-full.yml:8	Fixed
#2	.github/workflows/test.yml:11	Fixed
#3	.github/workflows/test.yml:31	Fixed
